         2 . The device of  claim 1 , wherein the ring shape includes a circular ring shape or a rectangular ring shape. 
     
     
         3 . The device of  claim 1 , wherein the compression member is configured to act in response to one or more of a plurality of trigger actions to control the plurality of light sources to emit light in one or more corresponding manners. 
     
     
         4 . The device of  claim 3 , wherein the plurality of trigger actions include:
 a first trigger action that triggers the compression member to control a predetermined number of the plurality of light sources to emit light to indicate the power of the battery;   a second trigger action that triggers the compression member to control the plurality of light sources to emit light alternately to light up corresponding light transmission areas; and   a third trigger action that triggers the compression member to control the battery to supply power to an external device via a power supply interface.   
     
     
         5 . The device of  claim 4 , wherein the predetermined number is positively correlated to the power of the battery. 
     
     
         6 . The device of  claim 3 , wherein the plurality of trigger actions individually or synchronously trigger the compression member. 
     
     
         7 . The device of  claim 3 , wherein the compression member is further configured to be triggered to control the battery to stop supplying power to the external device. 
     
     
         8 . The device of  claim 1 , wherein:
 the plurality of light sources are configured to remain off in a sleep mode without receiving any trigger action; or   the plurality of light sources are configured to remain on to indicate the power of the battery.   
     
     
         9 . The device of  claim 1 , wherein at least one of the plurality of light sources is configured to emit light of different colors used to indicate the power of the battery. 
     
     
         10 . The device of  claim 9 , wherein the different colors correspond to different levels of the power of the battery. 
     
     
         11 . The device of  claim 1 , further comprising:
 a substrate including the plurality of light sources; and   a light guide configured to guide and emit light from the plurality of light sources to indicate an operation status of the battery.   
     
     
         12 . The device of  claim 11 , wherein the light guide includes a light guide member, wherein:
 the light guide member includes a top surface, a bottom surface, and a side surface;   the top surface faces away from the bottom surface;   the side surface is configured to connect the top surface and the bottom surface;   the side surface includes an outer side surface and an inner side surface;   the bottom surface is connected with the substrate;   one of the plurality of light sources is configured to emit light toward the outer side surface to enter the light guide member; and   the light having entered the light guide member is emitted from the top surface after being reflected by the inner side surface to indicate the operation status of the battery.   
     
     
         13 . The device of  claim 12 , wherein:
 the outer side surface includes a light incidental surface;   the light source is aligned with the light incidental surface; and   the light emitted by the one of the plurality of light sources passes through the light incidental surface to enter the light guide member.   
     
     
         14 . The device of  claim 13 , wherein:
 the light incidental surface includes a curved surface; and   an area covered by connection lines of the light source and an edge of the light incidental surface covers an illumination area of the one of the plurality of light sources.   
     
     
         15 . The device of  claim 12 , wherein the outer side surface includes a reflection surface configured to reflect the light entered the light guide member to prevent the light from being emitted from the reflection surface. 
     
     
         16 . The device of  claim 12 , wherein:
 the light guide member as a whole has a ring shape; and   the compression member is arranged at a center of the light guide member.   
     
     
         17 . The device of  claim 16 , wherein the light guide further includes an opaque blocking member configured to divide the top surface of the light guide member into a plurality of sub top surfaces. 
     
     
         18 . The device of  claim 17 , wherein:
 the plurality of light sources are arranged around the light guide member at intervals; and   each of the sub top surfaces corresponds to a position of the one of the plurality of light sources.   
     
     
         19 . The device of  claim 16 , further comprising:
 a switch configured to be triggered to control the light source to emit light, the switch being arranged at the substrate and corresponding to a position of the compression member;   wherein the compression member is configured to be pressed to generate an elastic deformation to trigger the switch.   
     
     
         20 . A battery assembly comprising:
 a housing body;   a battery mounted at the housing body; and   an indication device mounted at the housing body and connected to the battery, and including:
 a compression member; and 
 a plurality of light sources arranged in a ring shape to surround the compression member and configured to indicate power of the battery.
